diy flow bench

[Matt Boland]

Does anybody know if anybody has built a diy flowbench ? I had an idea
that you could use an electric motor with an air pump on it and measure
the current drawn by the motor. You could use it uncalibrated in just a
good, better mode or maybe you could calibrate it by flowing known
items. It would be easy to hook up a PC and have a proffesional looking
display. The bench part would be easy to build and you could mount the
motor/pump underneath. Any thoughts?
